WATER-FILTER.

Specification of Letters Patent.

Patented Nov. 3, 1908.

To all whom it may concern:

Be it known the} I, FRANK C. FARNELL, a. citizen of th. United States,residing at the city of Los Angelcs, in the county of Los Angclcs andState of California, have invented certain new and useful Improvementsin ater-Filters, of which the following is a specification.

This invention relates to water filters, and consists of a stone- Warefilter especially adapted for domestic use, and characterized byimprovement with respect to the means for straining and filtering thewater, and with respect to the construction for supporting and holdingthe water and the filtering mediums. The device has the advantage ofsimplicity of construction, and its parts may be readily separated bysimply lifting one from the other. and when separated can be readilycleaned. The filtering material can also be quickly removed and renewedWhenever desired.

The invention is illustrated in the accom- 'ianying drawings in whichFigure 1 is a side i-lovation of the device. Fig. 2 is a centralvertical section. Figs. 3 and 4 are detail in elevation of the filteringcartridge and till settling tank.

It t'crring' soccifically to the drawings, G iud ratcs a 1 on ware jaror filtered Water container the mouth of which receives a car tri'lg'e.consisting of a stone-ware cu I) having a drip hole 1/ in the bottom andhaving air vents I) in the rim where it rests upon the top of the in r.The cup I) contains an inn-rtcd porous cup F, over the drip hole (I, andis filled or packed with filterin material preferably consisting oflayers o'l lirokcn granite, charcoal. marhlc, charcoal, and granilc. inthe order nanwd, as indicated at 'l'li sl'olic ware settling tank llsets upon the warlridgo, having a flange 11 at the bottom to hold it inplace thereon, and this settling tank is provided with a stone warecover A ha ring an air root (1. The bottom of the strainer; The bottomof the tank 13 is raised around t e hole-H, so that the settlings orsedimen will not collcct around the hole but in thedeeper part near thesides of the tank. W'ater placed in the settling tank will flow slowlythrou 'h the sponge and into the filtering cartridge where it will bepurified by passing through the granular filtering material or bed andthence through the percolating cup F, and out the drip hole at d intothe jar G, from which it may be drawn as necessary through the cock g.

As apparent, there is an entire absence of metallic parts, andconsequently a freedom from any contamination incident to the corrosionor action of the metals. The arts can be quickly separated by simply liting one from the other, and so canbe easily cleaned whenever necessary.The filtering material in the cartridge can be emptied out and renewedin a few minutes time, and all parts of the device are capable of beinwashed by hand inside and out, without dit ficulty.

I claim A settling tank for a filter, having a hole in the bottom withalconical rim around the hole raised above the remainder of the surfaceof the bottom. straining material in the hole; and an inverted cupover-the said hole I and resting at its lower edge on the sides of therim below the top thereof.

In testimony whereof I affix my s1gnature, in presence of two witnesses.
